The sun-filled living room showcases new solid oak hardwood floors, original architectural trim, art-focused recessed lighting, and a wood-burning fireplace. Elegant crown molding leads to the formal dining room—perfect for entertaining.

The private dual-level primary suite offers a finished loft retreat with walk-in closet and ideal home office or reading room. The luxurious ensuite bath (2026) features marble finishes, custom quartz vanity, and oversized walk-in shower with integrated seating. The fully renovated lower level (2026) adds a large family room and half bath. An attached garage provides convenience, while the detached shed offers flexible space for a studio, gym, office, or workshop. Outside, enjoy a quiet flat backyard in one of Silver Spring’s most desirable tree-lined neighborhoods. Steps to Sligo Creek Park trails and playgrounds, with easy access to Forest Glen Metro, I-495, the future Purple Line, and Downtown Silver Spring dining and shopping. Rarely does a renovation of this caliber come to market. Move in, relax, and enjoy the best of Silver Spring living.
